ITIPQYEY I Patented Sept. 24, 1929 UNITED STATES PATENT OFFICE FRIEDRICHWILHELM WEBER, 0F BOCHUM, GERMANY, ASSIGNOR TO THE FIRM VER-EINIGTESTAHLWERKE AKTIENGESELLSCHAFT, OF DUSSELDORF, GERMANY ARRANGEMENT FORSECURING RAILWAY RAILS Application filed June 13, 1927, Serial No.

The invention has reference to an arrangement for securing or fasteningrallway rails, in which the base or flange of the rail is clamped fastby means of preferably wedge shaped parts which engage with bridgesfirmly secured to, or integral with, the sleepers or tie plates.

The invention consists in an improvement of this method of railfastening by which the stability and reliability of Working arecosiderably increased. For this purpose the invention comprises securingby suitable means the wedges engaged over the base or flange of the railand under the bridges, so as to preclude the possibility of the wedgesgetting loose even when the tracks have been in service for a long time.

In the drawings:

1 is a vertical cross section taken along line AB of Fig. 3, Fig. 2 is aside elevation, and Fig. 3 is a plan of an embodiment of the invention.

Fig. 4 is a vertical cross section taken along line AB of Fig. 6, Fig. 5is a side elevation, and Fig 6 is a plan of a modification of theinvention.

Fig. 7 is a vertical cross section taken along line AB of Fig. 9, Fig. 8is a side elevation, and Fig 9 is a plan of a further modifica-. tion ofthe invention.

Figures 1, 2 and 3 show a method of securing the rails to the sleepersby means of wooden wedges. In these figures, a designates a wedge-shapedmeans, hereafter called a securing wedge which is inserted under eachridge b, in the manner shown by the drawings.

The bridges Z) are portions of the base late, one near each outer sideof the rail base, which are raised from the rest of the base plate. Thebridges are preferably integral with the base plate but may, however, beformer by fastening suitable members to the outer side of the base plateby any suitable means.

The securing wedges a engage the lower flange 0 of the rail and arepreferably provided with an upward extension. Wooden wedges g, whichpreferably have a crosssection as shown in Fig. 1, are driven between198,580, and in Germany June 1 5', 1926.

the inner face 6 of the upward extension of the securing wedge a and theweb I) of the rail, and also engage the lower flange c of the rail.Inner face e of each securing wedge is preferably roughened to preventany slipping of the wedge 9 after it has been driven into p ace.

Figures 4, 5 and 6 show an embodiment of the invention similar to thatshown in Figures 1, 2 and 3 in that an element is inserted between therail and each securing wedge, which element exerts an outward pressureagainst the securing wedge. I

In these figures, which show the method of securing the rails at thejoints thereof, fish plates are provided as is customary at rail joints,but these fish plates h are so shaped that they engage the lower flangeof the rail and the securing Wedges. When these fish plates are boltedto the rail in the ordinary manner, they exert an outward pressureagainst the securing wedges a, thus locking the securing wedges a underthe bridges b. The fish plates h fit so snugly that drawing their middleportions together by means of the customary bolts the upper and loweredges thereof are forced out so that the corresponding contour of thebottom edge is firmly pressed against the top of the wedge. In'Figures4, 5 and 6 the fish plates are shown as engaging the lower flange of therail and the top of the rail, but it will be understood that these fishplates may also engage the web of the rail, so long as they exert awedge effect against the securing wedges.

Figures 7, 8 and 9 discloses a further modification of the means forlocking the securing wedges a under the bridges b of the base plate. Inthis construction a screw bolt 71 is inserted between the web d of therail and 90 each of the securing wedges a, a suitable recess for the endof the screw bolt 71 being provided in the inner face of each securingwedge. A nut is is mounted on each of said screw bolts and is providedwith a point )5 which engages a small recess in the web of the rail, sothat the effective length of the screw bolt can be varied by suitablerotation of the nut is so as to lock the securing wedges a beneath thebridges b. The drawings show 100 Lil LII

a square recess in the inner face of each securing wedge 02 for therespective end of each screw bolt but, of course, any other suitablerecess may be provided.

The outer end of each securing Wedge a preferably rests upon plates ZWhich are Welded to the base plate, but these plates Z may be omittedand the outer end of each securing wedge permitted to rest directly uponthe base plate as shown in Figures 1-9 inclusive.

It will be seen from all the figures that the bridges are located closeto the edges of the flangeso of-the rail, and by this means applicantensures against the lateral displacement of the rail, the said bridgesacting as guides for the rails What I claim and desire to secure byLetters Patent of the United States is: 1. An arrangement for securingrailway rails to base plates, comprising bridges rigid with the baseplate and adjacent the flange of the rail to prevent lateraldisplacement thereof, Wedge-shaped means engaging the bridges and thelower flanges of the rail, and means engaging the rail and exerting apressure against the said wedge-shaped means for securing the latter tothe bridges. 2. An arrangement for securing railway rails to baseplates, comprising bridges rigid with the base plate and adjacent theflanges of the rail to prevent lateral displacement thereof, wedgeshaped means engaging the bridges and the lower flanges of the rail, and

' threaded means engaging the rail and exerting a pressure againstthesaid Wedge shaped means for securing the latter to the bridges.

3. An arrangement for securing railway rails to base plates, comprisingbridges rigid with the base plate and adjacent theflange of the rail toprevent lateral displacement thereof, wedge-shaped means engaging thebridges and the lower flanges of the rail, and a screw bolt between theweb of the railand the wedge-shaped means adapted to be adjusted so asto exert a pressure against said wedge-shaped means,
